Diffuse Large B-Cell Lymphoma
Conditions
Brief summary
The purpose of this study is to compare the efficacy and safety of genotype-guided targeted agents in combination with polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola RCHP-X) versus Pola RCHP in Chinese patients with previously untreated diffuse large B-cell lymphoma (DLBCL).

Inclusion criteria
* Signed Informed Consent Form * Age 18-75 years at the time of signing Informed Consent Form and willingness to comply with study protocol procedures * Previously untreated participants with CD20-positive DLBCL * IPI score 2-5 * ECOG Performance Status of 0, 1, or 2 * After 1 cycle of Pola-R-CHP, ctDNA decreased by \< 3.0 LFC * Life expectancy ≥ 6 months * Left ventricular ejection fraction (LVEF) ≥ 50% on cardiac multiple-gated acquisition (MUGA) scan or cardiac echocardiogram (ECHO) * Adequate hematologic function (unless due to underlying disease, as established for example, by extensive bone marrow involvement or due to hypersplenism secondary to involvement of the spleen by DLBCL per the investigator for which blood product transfusions are permitted) defined as follows: * Hemoglobin ≥ 9.0 g/dL without packed RBC transfusion during 7 days before first treatment * ANC ≥ 1.0 x 10\^9/L * PLT ≥ 75 x 10\^9/L
Exclusion criteria
* Contraindication to any of the individual components of Pola-RCHP or Zanubrutinib/Lenalidomide/ Decitabine * Prior solid organ transplantation or SCT * Current diagnosis of the following: Follicular lymphoma grade 3B; mediastinal grey zone lymphoma; primary mediastinal (thymic) large B-cell lymphoma; Burkitt lymphoma; PCNSL * Significant or extensive history of cardiovascular disease such as New York Heart Association Class III or IV cardiac disease or Objective Assessment Class C or D, myocardial infarction within the last 6 months prior to the start of Cycle 1, unstable arrhythmias, or unstable angina * History or presence of an abnormal ECG that is clinically significant in the investigator's opinion * Any of the following abnormal laboratory values (unless any of these abnormalities are due to underlying lymphoma): * Serum AST and ALT ≥ 2.5 x ULN * Total bilirubin ≥ 1.5 x ULN * Serum creatinine clearance \< 30 mL/min (using Cockcroft-Gault formula) * Any active infection within 7 days prior to Cycle 1 Day 1 that would impact participant safety * Positive test results for chronic hepatitis B infection (defined as positive hepatitis B surface antigen \[HBsAg\] serology)：Participants with occult or prior hepatitis B infection (defined as positive total hepatitis B core antibody and negative HbsAg) may be included if hepatitis B virus (HBV) DNA is undetectable at the time of screening. Such participants must be willing to undergo HBV DNA testing every month and appropriate antiviral therapy as indicated * Positive test results for hepatitis C (hepatitis C virus \[HCV\] antibody serology testing)：Participants positive for HCV antibody are eligible only if PCR is negative for HCV RNA * Participants with a history of progressive multifocal leukoencephalopathy * Pregnancy or breastfeeding, or intention of becoming pregnant during the study or within 12 months after final dose of Pola-RCHP-X * Other concurrent and uncontrolled medical conditions that, in the opinion of the investigator, would affect the patient's participation in the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival（by IRC） | From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months) | PFS, defined as the time from randomization to the first occurrence of disease progression or relapse using the 2014 Lugano Response Criteria or death due to any cause, whichever occurs first; as determined by the investigator |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival（by the investigator） | From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months) | PFS, defined as the time from randomization to the first occurrence of disease progression or relapse using the 2014 Lugano Response Criteria or death due to any cause, whichever occurs first; as determined by the investigator |
| Complete response rate | End of treatment visit (6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days] | CR rate at the end of treatment by FDG-PET defined as the proportion of participants with CR at the end of treatment according to the 2014 Lugano Response Criteria; as determined by the investigator and IRC (separately) |
| Event-free survival | up to approximately 24 months | defined as the time from date of randomization to the earliest occurrence of any of the following: Disease progression/relapse as determined by the investigator and IRC (separately) Death due to any cause The primary efficacy reason determined by the investigator, other than disease progression/relapse, that leads to initiation of NALT If biopsy is obtained after treatment completion and is positive for residual disease regardless of whether NALT is initiated or not |
| Overall survival | up to approximately 3 years | OS defined as the time from randomization to death from any cause |
| Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v5.0 | From enrollment to study completion, a maximum of 3 years | An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. |
| Objective response rate | End of treatment visit (6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days] | ORR at treatment completion or discontinuation defined as the proportion of participants with partial response (PR) or CR at the end of treatment according to the 2014 Lugano Response Criteria; as determined by the investigator and IRC(separately) |
